“Deathstar, Rising!”

★ 1st appearance — Black Tom Cassidy

About this Issue

X-Men #99 carries the cameo debut of Black Tom Cassidy, Banshee's Irish criminal cousin who would evolve into one of the X-Men's most persistent Bronze Age antagonists. The issue also plants the seed for the original-vs.-new X-Men confrontation resolved in the milestone #100, making it an essential bridge issue in the Claremont–Cockrum run. Its space-set battle against Stephen Lang's Sentinels aboard a stolen SHIELD orbital platform pushed the new team's adventures into genuinely cosmic territory for the first time, and Storm's discovery that she can command solar weather in the vacuum of space expanded her power set in ways that resonated for decades. Together, these elements make it a pivotal chapter in the run that would transform the X-Men from a cancelled also-ran into Marvel's dominant franchise.

In "Deathstar, Rising!", the X-Men launch a high-stakes rescue mission to SHIELD’s orbital platform, racing against time to save their teammates from the enigmatic Lang. With Sentinels closing in—some eerily modeled after the original X-Men—the team faces a chilling confrontation that tests their resolve and unity. Written by Chris Claremont and brought to life by Dave Cockrum’s dynamic art, this 1976 issue delivers tense action and psychological stakes, with cover art by Cockrum capturing the urgency of the moment.

History

Written by Chris Claremont and pencilled by Dave Cockrum — with inks by Frank Chiaramonte and letters split between Gaspar Saladino and Irving Watanabe — the issue was edited by Marv Wolfman and published with a June 1976 cover date. Claremont had taken over the relaunched series from issue #94 onward after Len Wein, who co-created the new team, handed him the reins, reasoning that the book's low commercial profile made it a safe assignment for a younger writer. By #99 the title was gaining serious momentum; a firsthand 1976 convention account records that a Claremont–Cockrum panel was packed and greeted with cheers when Cockrum announced he had inked the following issue himself. The Black Tom Cassidy cameo at the issue's close was Claremont and Cockrum's deliberate setup for the Cassidy Keep storyline beginning in #101, with Tom conceived from the start as a personal nemesis for Banshee rooted in family rivalry and disputed inheritance.

Written by Chris Claremont; pencils and cover by Dave Cockrum; inks by Frank Chiaramonte; colors by Michele Wolfman (with some index sources crediting Wrightson as a historical variant attribution); letters by Gaspar Saladino (page 1) and Irving Watanabe; edited by Marv Wolfman.
Story title: 'Deathstar, Rising!' — the second chapter of a three-part arc spanning X-Men #98–100.
Storm discovers she can manipulate solar weather in outer space, not just terrestrial weather — a significant expansion of her powers established in this issue.
The X-Men infiltrate a former SHIELD orbital platform by disguising themselves as the crew of Dr. Peter Corbeau's Starcore shuttle; Corbeau appears as a guest character throughout.
The issue ends with the new X-Men confronting robot duplicates of the original team (X-Sentinels built by Stephen Lang to resemble Cyclops, Marvel Girl, Iceman, Angel, Beast, and Professor X), setting up the landmark X-Men #100.
Real-life newscasters Roger Grimsby and Geraldo Rivera appear in cameo as TV reporters covering anti-mutant hysteria — a grounding technique Claremont used repeatedly to tie mutant persecution to contemporary media.
